Title: Detection method for completion point of chemical and mechanical polishing
Inventor: CHIN RAIJO
IPC: B24B37/013
Filed: 1997-11-20
Abstract: PROBLEM TO BE SOLVED: To monitor the abrasion of a pad in-situ by measuring emissivity of the pad in an abrasion ring. SOLUTION: Occurrence of abrasion increases the emissivity of a pad 13. In a case of an opaque body, the increase in the emissivity reduces the reflectivity. As bristles 11 are raised caused by a repetitive treatment by conditioner, a light incident on the pad 13 is captured in the bristles 11 so as to incur a possibility of not being emitted again. This effect correlates with the emissivity of the pad. The tracking of the emissivity in one or more regions in an abrasion ring allows to monitor the abrasion rate of the polishing pad 13 and surely inform the end of the useful life of the pad 13 so that the pad 13 can be replaced.

Title: Ultrasonic current sensor
Inventor: TODA KOJI
IPC: G01R15/22
Filed: 1999-12-22
Abstract: PROBLEM TO BE SOLVED: To sense a current flowing in the periphery of an ultrasonic fiber by utilizing the ultrasonic fiber. SOLUTION: An elastic vibration is driven to an input piezoelectric vibrator 1 when an input electric signal is applied to a transmission electrode 2. The elastic vibration propagates from an input diaphragm 5 to an output diaphragm 10 via the ultrasonic fiber 11, then propagates to an output piezoelectric vibrator 6 and is detected as a delay electric signal between a reception electrode 7 and an output grounding electrode 9. The delay electric signal is transmitted to a signal-analyzing means. If the ultrasonic fiber 11 is placed in the middle of a magnetic field, the frequency of the delay electric signal changes in accordance with a field strength. Therefore, the field strength in the periphery of the ultrasonic fiber 11, i.e., a current flowing in the periphery of the ultrasonic fiber 11 can be sensed from a change of the frequency of the delay electric signal.

Title: Retaining wall structure
Inventor: YASUNO TAKEO
IPC: E02D17/18
Filed: 1998-12-25
Abstract: PROBLEM TO BE SOLVED: To contrive the reduction of a total cost and structurally enhance stability by back-filling foaming plastic blocks on the rear face of a retaining wall having a vertical wall and a foundation plate. SOLUTION: A lump of soil 5 is back-filled upward of the foundation plate 3 of the rear face of a retaining wall, and foaming plastic blocks 4 are back- filled on the rear face side rather than the upper part of the foundation plate 3. The lump of the soil 5 back-filled upward of the foundation plate 3 acts as load resisting mainly to a violent fall moment, and the foaming plastic blocks 4 of ultra-lightweight back-filled on the rear side rather than the upper part of the foundation plate 3 contribute to reduction of soil pressure to further contrive violent fall prevention. The foaming plastic block 4 is preferably excellent in strength, excellent in water resistance, and particularly, it is suitable for a polystyrene foaming body.  Thereby, retaining wall structure of high safety against a violent fall and slip can be realized on foundation ground in which strength is relatively large at a lower cost.

Title: Bonding member, multichip module with the bonding member and bonding method using the bonding member
Inventor: TAKABAYASHI HIROSHI
IPC: H01L25/04
Filed: 1997-12-27
Abstract: PROBLEM TO BE SOLVED: To perform a temporary bonding operation by a simple apparatus and to suppress a rise in the production cost of a multichip module. SOLUTION: When electric elements 2, 3, 4, 5 are bonded to a board 1, an ACF 10 as shown in the figure is used. The ACF 10 is constituted in such a way that a bonding layer 11 which is adhesive at room temperature and an anisotropic conductive layer 12 which is formed by dispersing and mixing conductive particles 12b into and with a resin 12a are laminated. When the electric elements 2, 3, 4, 5 are pressed to the board 1 so as to sandwich the ACF 10, both are bonded temporarily by the adhesive property of the bonding layer 11. Consequently, it is not required to perform a heating operation and a pressurizing operation when both are bonded temporarily as different from an ACF 10 in conventional cases.  Both are bonded temporarily by a simple and low-cost apparatus which is provided with only a pressurizing function and which is not provided with a heating function, and a rise in the production cost of a multichip module can be suppressed.

In the base layer used here, the crystal is uniform, the closest density plane is parallel to the substrate and alignment is also uniform because it is composed of the FCC or HCP phase where the shortest atom radius is different in 15% to 25% from that of the Co alloy magnetic layer. Therefore, alignment of magnetic particle of the magnetic layer formed on this base layer and amplitude of magnetic unisotropy may also be set uniform. Moreover, coercive force may be set large and rectangular ratio can also be improved.
